18、 female students learn: 在最新一項(xiàng)關(guān)于小學(xué)生學(xué)數(shù)學(xué)的研究中，芝加哥大學(xué)的心理學(xué)家Sian Beilock和Susan Levine 發(fā)現(xiàn)，女教師的想法和女學(xué)生的學(xué)習(xí)之間有著驚人的聯(lián)系：If a female teacher is uncomfortable with her own math skills, then her female students are more likely to believe that boys are better than girls at math.如果女教師對自己的數(shù)學(xué)能力感到焦慮，她的女學(xué)生很可能認(rèn)為男孩子數(shù)學(xué)比女孩學(xué)得更好。

19、If these girls keep getting math-anxious female teachers2 in later grades, it may create a snowball effect on their math achievement3 said Levine. 如果一直由對數(shù)學(xué)有焦慮的女教師教授數(shù)學(xué)，就會(huì)對她們的數(shù)學(xué)成績產(chǎn)生雪球效應(yīng)，Levine說。 In other words, girls may end up learning math anxiety from their teachers4. 換言之，女孩子們最后從老師那里獲得的是對數(shù)學(xué)的焦慮。The

20、study suggests that if these girls grow up believing that boys are better at math than girls are,then these girls may not do as well as they would have if they were more confident. 該研究表明，如果女孩子們在一個(gè)認(rèn)為男孩比女孩數(shù)學(xué)好的環(huán)境中成長，那么她們的數(shù)學(xué)可能會(huì)不如在更自信的狀態(tài)下學(xué)得好。Just as students find certain subjects to be difficult, teacher

21、s can find certain subjects to be difficult to learn - and teach. The subject of math can be particularly difficult for everyone. Researchers use the word anxiety to describe such feelings: anxiety is uneasiness or worry.如同學(xué)生，教師也會(huì)覺得某些學(xué)科難學(xué)和難教，這就是研究者所言的焦慮：不自在或擔(dān)心。The new study found that when a teacher

22、 has anxiety about math, that feeling can influence how her female students feel about math. 此研究發(fā)現(xiàn)，教師對數(shù)學(xué)的焦慮能夠傳染給她的女學(xué)生們。The study involved 65 girls,52 boys and 17 first- and second-grade teachers in elementary schools in the Midwest. The students took math achievement tests at the beginning and end o

23、f the school year, and the researchers compared the scores.該研究的研究對象包括65個(gè)女孩，52個(gè)男孩和17位在中西部教一二年級(jí)的教師。學(xué)生們在學(xué)年的開始和結(jié)束時(shí)都進(jìn)行數(shù)學(xué)測試，研究者們比較得分。The researchers also gave the students tests to tell whether the students believed that a math superstar had to be a boy. 研究者們測試學(xué)生是否認(rèn)為數(shù)學(xué)明星一定會(huì)是男孩。Then the researchers turned

24、to the teachers: To find out which teachers were anxious about math, the researchers asked the teachers how they felt at times when they came across math, such as when reading a sales receipt5. 然后研究者們測試教師，試圖找出哪些教師對數(shù)學(xué)感到焦慮，研究者們問教師們當(dāng)碰到數(shù)學(xué)問題諸如閱讀銷售清單時(shí)的感受，A teacher who got nervous looking at the numbers on

25、 a sales receipt, for example, was probably anxious about math.如果一位教師一看到銷售清單的數(shù)字就感到緊張，那么她很可能對數(shù)學(xué)存在焦慮。Boys, on average, were unaffected by a teachers anxiety. 平均來說，教師的焦慮不會(huì)影響到男孩子。 On average, girls with math-anxious teachers scored lower on the end-of-the-year math tests than other girls in the study di

26、d. 但是，一般說來，如果教女孩子的教師有數(shù)學(xué)焦慮癥，那么女孩子們在學(xué)年結(jié)束時(shí)測試得分比其他的女孩要低。Plus,on the test showing whether someone thought a math superstar had to be a boy,20 girls showed feeling that boys would be better at math - and all of these girls had been taught by female teachers who had math anxiety.另外，在關(guān)于是否認(rèn)為數(shù)學(xué)明星應(yīng)該是男孩的測試中，有20

27、個(gè)女孩認(rèn)為男孩數(shù)學(xué)比女孩好，這20個(gè)女孩的老師都是女性，且都患有數(shù)學(xué)焦慮癥。This is an interesting study, but the results need to be interpreted as preliminary and in need of replication with a larger sample6, said David Geary, a psychologist at the University of Missouri7 in Columbia.來自密蘇里大學(xué)的心理學(xué)家David Geary說這是一個(gè)有趣的研究，但是這只是初步結(jié)果，需要用更大的調(diào)查

28、樣本進(jìn)行重復(fù)驗(yàn)證。特別說明：完形填空記憶難度大，且每年都會(huì)存在大量換空的情況，（我們會(huì)有應(yīng)對策略，對于此題型文章不用太多關(guān)注，重點(diǎn)先放在閱讀理解重點(diǎn)文章的內(nèi)容熟悉，至少要知道每一段的中文意思是什么可參考翻譯，問題都問了些什么?？糀的同學(xué)順帶看下B、C的文章，考B的同學(xué)順帶看下C的文章）第十二篇 Free Statins With Fast Food Could Neutralize Heart Risk Fast food outlets could provide statin drugs free of 1 so that customers can reduce the heart di

B本文介紹說，吃漢堡包等快餐食品容易引發(fā)心臟病，而服用statin能降低心臟病發(fā)作的風(fēng)險(xiǎn)，一正一負(fù)正好抵消。statin 價(jià)格便宜，文章建議快餐店像免費(fèi)供應(yīng)調(diào)味品那樣免費(fèi)供應(yīng)statin0 free o

39、f charge 是固定搭配，意為“免費(fèi)”。選擇charge 是對的。2. C 本題要選suggest ，因?yàn)槠渌齻€(gè)選項(xiàng)在意思上都不合適。此外，本句主句的謂語動(dòng)詞用了could (provide) ，委婉地含有“建議”的意思。所以suggest 是個(gè)不二的選擇。3.B 與降低unhealthy LDL cholesterol 搭配的一定是amount（量），而不可能是number（數(shù)字）、volume（體積）或product （乘積）。4.D從上下文判斷，要降低（lower）的當(dāng)然是risk。lower frequency（降低頻率）、lowertreatment（降低治療）或lower d

40、iagnosis （降低診斷）與上下文的意思都不匹配。5. B 本句表達(dá)的意思是：Dr Darrel Francis 在他的論文中說，經(jīng)過計(jì)算，一粒statin 降低心臟病發(fā)作的風(fēng)險(xiǎn)足以抵消吃一個(gè)奶酪漢堡包和喝一杯奶昔所增加的患心臟病的風(fēng)險(xiǎn)。所以本題的答案是enough。6. C 顧客不可能在快餐店里preparing cheeseburger 或cooking cheeseburger，而buyingcheeseburger不會(huì)增加心臟病風(fēng)險(xiǎn)。所以，只有eating cheeseburger 才合乎上下文的意思。7.A從上下文判斷，被cut out（去除）的effects一定是unhealt

41、hy effects，所以，unhealthy是本題的答案。8.D本句中的in terms of 意為“就而言”，要與后半句“一正一負(fù)相互抵消”的意思相匹配，所以只能是“就患心臟病的可能性而言”。possibility 是答案。9. A本句的意思與第五題的意思相同，即statin降低心臟病發(fā)作的風(fēng)險(xiǎn)與快餐增加的心臟病的風(fēng)險(xiǎn)在程度（degree）上大致相當(dāng)。如果選擇其他三個(gè)選項(xiàng)，意思變成了，“尺寸(dimension）上、角度（angle）上或范圍（range）上大致相當(dāng)”，就說不通了。1O.D 填詞所在的句子的意思告訴我們，具有諷刺意味的一點(diǎn)是：顧客可以隨心所欲地免費(fèi)享用不健康的調(diào)味品。as

42、one likes 是固定用法，意為“隨某人所愿，隨某人所喜歡”。所以，like 是答案。其余三個(gè)選項(xiàng)用在本句中都不合適。11.B transported （運(yùn)輸）、preserved （保存）或converted （轉(zhuǎn)換）填人句子中，意思都不順。只有填入provided （提供）符合句意。provided 是答案。12.C 到快餐店去就餐的人當(dāng)然是customer。13.A 為了降低開車和吸煙的風(fēng)險(xiǎn)，人們被鼓勵(lì)要采取一些安全措施。作者借此說明為了降低食用快餐的風(fēng)險(xiǎn)，我們也要采取措施。根據(jù)這層意思，選擇measures是正確的。takemeasure的意思是“采取措施”。其他三個(gè)選項(xiàng)都不合適：

43、take care是“注意，小心”，takeadvantage 是“利用”，take turns 是“輪流，依次”。14.B 本題很明顯要選wearing，因?yàn)樯舷挛牡囊馑际恰跋瞪习踩珟А?。buying a seatbelt,cleaning a seatbelt和changing a seatbelt都與上下文的意思相去太遠(yuǎn)。15. C通篇文章都在闡述statin能降低患心臟病的風(fēng)險(xiǎn)。所以，lowering（降低）是答案?？觳图用赓M(fèi)降膽固醇藥物可以降低罹患心臟病的風(fēng)險(xiǎn)倫敦帝國理工學(xué)院的研究者們在一項(xiàng)新研究中建議，快餐店可以免費(fèi)供應(yīng)降膽固醇藥物以此降低顧客食用油膩食品罹患心臟病的風(fēng)險(xiǎn)。降膽固醇

44、藥物能減少不健康的低密度脂蛋白膽固醇在血液中的含量。大量的試驗(yàn)數(shù)據(jù)已經(jīng)證明，降膽固醇藥能有效降低罹患心臟病的風(fēng)險(xiǎn)。在美國心臟病學(xué)雜志發(fā)表的一篇論文里，Darrel Francis博士和他的同事們估訂，一粒降膽固醇藥降低的罹患心臟病的風(fēng)險(xiǎn)，足以抵消食用漢堡和飲用奶昔所提高的罹患心臟病的風(fēng)險(xiǎn)。Francis博士來自帝國理工學(xué)院的國家心肺學(xué)院，是本次研究的資深發(fā)起人。他認(rèn)為：“降膽固醇藥物不能消除所有漢堡和炸土豆條帶來的不健康的影 響，最好遠(yuǎn)離所有油膩食物。但是，就罹患心臟病的幾率而言，我們得出這樣的結(jié)論：服用降膽固醇藥物降低心臟病發(fā)作的風(fēng)險(xiǎn)與快餐增加的患心臟病的風(fēng)險(xiǎn)在程度 上大致相當(dāng)?！薄熬哂兄S刺意味的是，人們在快餐店里可以隨意拿取對健康有害的調(diào)味包，但是對健康有利的降膽固醇藥物卻是處方藥。既然對健康有害的調(diào)味包可以隨意免費(fèi) 拿取，那么降低心臟病發(fā)作的降膽固醇藥物免費(fèi)隨意拿取也是合理的。在每個(gè)顧客身上都花不了5便士，也就是一小袋糖的價(jià)格”，F(xiàn)rancis博士說道。當(dāng)人們從事諸如駕駛和吸煙等危險(xiǎn)行為時(shí)，別人會(huì)鼓勵(lì)他們系安全帶或選擇有過濾嘴的香煙以降低風(fēng)險(xiǎn)。服用降膽固醇藥物是降低油膩食物引發(fā)的心臟病發(fā)作風(fēng)險(xiǎn)的理性做法。
